GAS BURNER FOR HEATING DEVICES OF THE TUBULAR-TICK TYPE.

Application filed October 26, 1922.

To all whom it may concern:

Be it known that we, (a) Jnssn S. HAL- srnan and (6) JOHN F. Mona, citizens of the United States, residing at ((4) Oakland, 6) Pittsburg, in the county of (a) Alameda, (6) Contra Costa, and State of California, respectively, have invented certain new and useful Improvements in a Gas Burner for Heating Devices of the Tubular-Wick Type; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide an attachment for use in connection with a stove lamp of the central draft or tubular wick type, whereby the oil, under control of the wick, may be converted into gas, (or

' vaporized) and consumed as gas remote from the wick and under conditons insuring complete combustion, producing a flame of maximum heat value or intensity with the minimum consumption of oil and without consuming, chairing or causing deterioration of the wick.

\Vith these objects in view the invention consists in a construction and combination of parts of which a preferred form is shown in the drawing, wherein:

Figure l is a View of a lampof the conventional form used in lamp stoves and the like, having fitted thereto a burner embodying the invention,

Figure 2 is an enlarged sectional view of the upper portion of the wick tube and burner,

Figure 3 is a plan view of the burner cap,

Figure 4 is a horizontal section of a portion of the burner on the plane indicated by line H of Figure 2.

The burner consists, essentially, of annular form adapted to fit double walled wick tube 11 of the central draft stove lamp which uses the tubular wick l2, and provide with an annular mixing chamber 13, an annular wick chamber 14: and vaporizing passages 15 connecting said chambers and formed in a metallic ring 16 or otherwise in such relation to the zone of combustion as to convert the oil presented by the wick into gas in its passage therethrough toward the mixing chamher.

The outer and inner walls of the wick chamber fit over but do not snugly embrace of a cap over the ordinary Serial No. 587,039.

the wick tube so that there may be provision for the influx of air to mix withthe gas in chamber 13 of which by cap plate 17 is provided with burner orifices 18 of relatively restricted area'calculated to retain a ing chamber. The mixture burns, above the orifices to form an incandesent flame of maximum heat value for the fuel consumed, and the relative flow of fuel and inlet'of air may be regulated and properly proportioned by the adjustment of the wick and hence the vertical movement of the cap with rela tion to the wick tube.

An economical construction of the burner is suggested in the drawing, wherein'the inner and outer annular walls 19 and 20 which jointly form the corresponding walls of the mixing and wick chambers, are sep arated by the spacing rings 16 in which the vaporizing passages are formed, while the removable cap plate 17 completes the structure and may be produced readily by the stamping process.

The flame spreader 21, of conventional form and used in the ordinary lamp to which the improved burner is applicable, may be fitted in the central opening of the burner, as shown in Figure 1, to perform its usual function.

The burner, thus can be applied to the on dinary stove lamp without necessitating any alteration or preparation of the latter.

It will further be noted that the vaporizing passages are of relatively small diameter compared with their length to pro vide against back lighting or the communication of flame back to the wick and burning of gas at the lower ring.

It should be apparent from the foregoing description, taken in connection with the accompanying drawing, that a tubular wick heating device equipped with our improved burner may be eflectively used for cooking stoves, heating stoves, hot air furnaces, steam boiler furnaces, and the like; that the burner may be used in connection with any of the well known heating devices of the tubular wick type now on the market and that crude oil as well as kerosene may be employed as fuel for such devices.

Having thus described the invention, What we claim as new is 1. A burner for central draft oil heaters consisting of a movably mounted cap adaptthe upper Wall formed slight pressure in the mixedge of the burner ed to rest on the wick, the wick having a mixing chamber provided and burner means associated therewith and connected with the wick zone by vaporizing passages of flame excluding dimensions.

2. A burner for central draft heaters having a Wicktube comprising inner and outer walls, the same consisting of an annular cap slidably fitting the spreader of the heater and provided with upper and lower, respectively mixing and wick chambers connected by upright passages, the wick chamber being adapted to receive the upper end of the wick tube and the contained wick so that the cap will rest on the wick, and the mixing chamber having exposed burner orifices.

3. A burner for central draft heaters having a wick tube comprising inner and outer walls, the same consisting of an annular cap provided with upper and lower, respectively mixing and wick chambers connected by upright passages, the wick chamber being adapted to receive the upper end of the wick tube and the contained wick and the mixing chamber having exposed burner orifices, the upper end of the wick being movable within said wick chamber with relation to the lower ends of said passages.

41. A burner for central draft heatershaving a wick tube comprising inner and outer walls, the same consisting of an annular cap provided with upper and lower, respectively mixing and wick chambers connected by upright passages, the wick chamber being adapted to receive the upper end of the wick tube and the contained wick and the mixing chamber having exposed burnerorifices, air inlet passages being provided for said wick chamber between the wick tube and the walls of the wick chamber.

5. A burner ring for interposition between the wick tube and the spreader of a central draft annular wick ,oil heater, having parallel annular mixing, and wick chambers of which the latter chambers being connected. by vaporizing passages.

6. A burner comprising a movably mounted cap having a mixing chamber and burner.

means associated therewith, said cap pro vided with a wick chamber to receive the upper endof the wick tube, and said burner means connected with the wick chamber by vaporizing passages of flame excluding die inenslons.

In testimony whereof we .aflix our signa tures in presence of two witnesses.
